Question: Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the same direction. Kara bikes at a speed of 15 km/h and Steven bikes at a speed of 30 km/h. How long will it take before Steven and Kara will be at the same place of the path next time?
Answers
============================================================
Explanation:
The path is 1800 km. Kara's speed is 15 km/h. If this speed is held the same throughout the path, then it will take her d/r = 1800/15 = 120 hours to travel the entire path until she gets back to her starting point.
For Steven, it takes him d/r = 1800/30 = 60 hours to make the same journey.
The LCM of 60 and 120 is 120
Every 120 hours, both Kara and Steven will be back at the starting point together.
Note: this is a very very large time value, and this is not considering the fact that the bikers slow down or stop to take a break.

What is the area of the shaded region to the nearest tenth of a foot?
Part a) Explain what formulas you will use to find the area of the shaded area.
Par b) Explain how you find the area of the shaded region. What was your thought process?
Answers
Area of rectangle = length*width
Area of circle = (π/4)*diameter²
b) The figure shows the width of the rectangle is 14 ft, the same as the diameter of the circle. The length of the rectangle is shows as 21 ft. The shaded area is the difference ...
Shaded Area = Area of rectangle - Area of circle
Shaded Area = (21 ft)*(14 ft) - (π/4)*(14 ft)²
Evaluating this expression, we have
Shaded Area ≈ 294 ft² - 153.9 ft² = 140.1 ft²

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed? (look at the image below)
The dependent variable is distance, the equation is x = 20y, and the dragonfly will travel 360 miles.
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.
The dependent variable is time, the equation is x = 20y, and the dragonfly will travel 360 miles.
The dependent variable is time, the equation is y = 20x, and the dragonfly will travel 480 miles.
Answers
so
y = 20x
y = distance (miles) and x = time (hours)
so if x = 24 then y = 20x = 20(24) = 480
answer
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.
Answer:
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.Step-by-step explanation:
According to the graph, the dependent variable is Distance in miles, because it's on the vertical axis. Additionally, the independent variable is time in hours, because it's on the horizontal axis. However, you always put time as independent, because nothing affects time.
To find the equation, we just need to find the slope, using two points (0,0) and (2,40).
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{40-0}{2-0}=20[/tex]
Therefore, the equation is [tex]y=20x[/tex], which shows a direct proportion between variables.
Now, in 24 hours, it would travel
[tex]y=20(24)=480[/tex]
It would travel 480 miles.
Therefore, the right answer is the second choice.

Answers
4 * s
where s is the side length.
Area is:
s * s
So, we can set both of these values to 196.
4s = 196
s = 49
s * s = 196
s = 14
So, Madison is correct.

a traffic light on a busy north-south street is programmed according to this pattern: green for 4 minutes followed by red for 2 minutes. mr gomez goes through this intersection on his way to an from work everyday. last week, he kept a record of the number of times it was green as he approached the intersection and the number of times he had to stop because the light was res. his record is as follows green green red green green green green green green green, what is the therorerical probability that the light will be green each time mr gonez approaches the intersection
Answers
The theoretical probability is the expected amount of times that the light would be green. The light is green for 4 minutes and red for 2 minutes for each series. That means 4 out of the total 6 minutes are green.

Food express is running a special promotion in which customers can win a free gallon of milk with their food purchase if there is a star on the receipt so far 147 of the first 156 customers have not received a star in the receipts what is experimental probability of winning a free gallon of milk
Answers
P(nw) = no wins / total
no wins = 147
Total = 156
Calculation for no wins
P(nw) = 147 / 156 = 0.9423
Calculation for winners.
P(w) = 1 - 0.9423
P(w) = 0.05769
Another way.
You could calculate the winners from the total
156 - 147 = 9
P(w) = 9/156 = 0.05769 Same answer as before. Pick the method you like best.

Equation 2: y = - 6x + 4
Equation both equations, we get:
- 8x - 2= - 6x + 4
-8x + 6x = 4 + 2
-2x = 6
x = -3

y= -8(-3) - 2 = 24 - 2 = 22
So, the solution to the given equations is (-3, 22)

Write an equation for a line g(x) perpendicular to f(x) = 4x − 5 and passing through the point (4, 20). plz.....
Answers
Now we need to find the equation of a line that has slope -1/4 and passes through the point (4, 20).
We use the point-slope form of the equation of a line, where m = slope, and the point is (x1, y1).
y - y1 = m(x - x1)
y - 20 = -1/4(x - 4)
-4y + 80 = x - 4
x + 4y = 84
Final answer:
The equation for the perpendicular line g(x) is g(x) = (-1/4)x + 21, found by using the negative reciprocal of the original slope and the point-slope form of a line.
Explanation:
To find the equation for a line g(x) that is perpendicular to f(x) = 4x - 5 and passes through the point (4, 20), we need to determine the slope of the perpendicular line and then use the point to find the specific equation.
Since the slope of the line represented by f(x) is 4, the slope of any line perpendicular to it will be the negative reciprocal, which is -1/4.
Now, we can use the point-slope form of a line equation, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point the line passes through.
Substituting the given point and the slope into the point-slope form, we get:
y - 20 = (-1/4)(x - 4)
Expanding this we have:
y - 20 = (-1/4)x + 1
Adding 20 to both sides to solve for y gives us the final equation of line g(x):
g(x) = (-1/4)x + 21
